DNA Markers for Genealogy

DNA Markers for Genealogy – Mitochondrial DNA Genealogy

Who else wants to know about DNA markers for genealogy? Here is a simple scientific test to trace your ancestors. Did you know that DNA From One Generation To The Other Is Almost Conclusive Evidence. This breakthrough in genealogy research has been making headlines for the past several years with some astounding proof of kinship between some very prominent historical figures.

DNA testing for family tree is not only convenient, but also simple. You find a genealogy testing company either in the phone book of on the Internet. Next, make an appointment and go to the company on your assigned day, fill out the forms, pay the fee and your good to go. The DNA genealogy test starts with a mouth swab of your mouth near the cheek. Many companies give you a kit so you can do the mouth swab at home and mail in the results to the laboratory. After the laboratory tests the DNA, the results are sent back to testee.

Wide DNA Databases Compare

The company doing the genealogy DNA testing will obviously need to have access to DNA databases which they will use to make comparisons and once these comparisons show their results, the company will then send you the results regarding whom your DNA swab matched with. You should realize that each and every cell is sure to have your DNA and whether it is your sperm or egg cells or even the sex cells, you will be providing your own unique DNA for further matching.

Parents Pinpointed

Listen closely. Genealogy DNA testing is helpful in pinpointing an individual’s parentage and it can be used extensively when you need to know who the mother is, and also in case of adoptions. Thus, it is easy to see how genealogy DNA testing can help with creating your family tree because your DNA will have been passed from one generation to the next and the information pertaining to your ancestors will be encoded therein.

The Egg The Sperm

When your sperm and also egg cell combine together, a new cell is created that will hold DNA from either parent and when genealogy DNA testing is performed in specialist laboratories, they will help provide evidence whether you are related to another person with a matching DNA. What’s more, the chances of two persons having identical DNA are very small with the exception of identical twins which are due to the fact that their DNA is identical because the fertilized egg had split and formed two fetuses obtained from a single sperm and also from the same egg.

Cutting Edge Medical Science Genealogy DNA Testing

Just imagine, as DNA is passed from generation to generation there is very little change in its structure. This is amazing and is the primary reason to use DNA markers for genealogy testing to explore your ancestry. In no time at all, the link between families can be nailed down and makes the construction of a family tree that much more reliable and accurate. And new advances are being made in medical science to enhance and improve the DNA testing for family tree.

Dr Geoff Swinfield will be lecturing on DNA and family history as part of the "Ask the Experts" workshops run by the Society of Genealogists at the forthcoming Family History Conference in Nottingham. He has a Ph.D. in genetics and has used this training to apply genealogical research to the study of families at risk from genetic diseases.
